Well, to be fair, I don’t know much about the series, save for I, V, VII, VIII, and X, but going with the spiritualism in the first film, it may not seem so out of place with me. Who knows what secrets the adults may be concealing from their young ones until the time is right for them to know?
Sorry, this is just me being half-Star Wars fan and BIONICLE fan. I don’t much by the movie series, but I like to include such ideas whenever I can.
P. S. To the original poster, it would be “shaman,” not “shawman.”
